' Tn a/ZZ wiz/0m 1' t may con/cern.:

Be' it known-that I, MICHEL BODY, a subi ject ofthe King ot Belgium, residing at Brussels, Belgium, have invented a new and useful Process and Means for the Combustion of Liquid Hydrocarbons, (for which patents have been applied for in Germany, No.15,90, dated May 4, 1898; in France, No. 267,653, dated July 18, 1898, and in Italy, Rg. XXXIX, No. (i, dated .Iune 10, 1898,) of which the following is a specilication.

. This invention relates to a process and 4means for the combustion of liquid hydrocarcarbon, instead of being atomized or vapor? ized, is decomposed in such a manner that it is for the most part converted into soot. T is is eiected by igniting the liquid hydrocarbon and allowing it to burn with a'small ame, so that a large quantity of soot is formed. This soot then forms an excellent combustible ma- .terial containing a high percentage of carbon in an exceedingly tine state of division. A

furnace constructed upon this principle is f illustrated in the accompanying drawings, in

which- Figure l is a longitudinal'section of the t`ur` nace. Fig. 2 is a transverse vsection of the furnace, and Fig. 3 isa sectional plan.

In front of the heating-chamber proper, a, which is to be heated, thereis arranged a foreohamber b, of .firepro'of material, which is heated red-hot bymreans; et' auxiliary grate through the medium of ordinary solid fuel.

In front of this iireplace, which is at once put out of operation when it has fullled its purpose of hea ing the brickwork, there is arranged a tray c, which is preferably made of cast-iron, the said tray being advantageously built in an opening in the brickwork or in the case of ships is mounted on adouble suspen- 'Ihe flame developed thereby is,

be burned tlows into the said tray from a vessel standing near the oven, boiler, dac. The shape of the tray is such that it is directed toward the liquid fuel, which flows laterally into it through the pipe d, not into the middle, but into theouter end thereof. lNhen the tray is full, or practically so, the liquid fuel ignitesand a considerable formation of soot takes place. This soot is by means of a steam-jet g, which is fitted in the space above the tray, blown into the hot fore-chamber l) for combustion. The steam-jet must be so directed that it does not enter the tray and disturb the liquid fuel. As soon as the soot passes into the hot chamber b itis burned, as the air necessary for its combustion is introduced into-.the combustion-chamber simulta neously With the steam. The quantity of air drawn in can be easily adjusted by regulating the pressure at which the steam is injected. With this arrangement, therefore, the hydrocarbon is not atomized or vaporized, but is decomposed, so as to form soot, carbon monoxid, and water. The soot and the carbon monoxid are then conveyed by the steam-jet into the chamber I), where they are heated and completely burned with the aid of the air drawn in without the formation of an intense thin dame. The combustion is so complete that no smoke issues trom the chimney v Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. The described process for burning liquid hydrocarbon such as petroleum residue, tar, and naphtha, dac., the same consisting in con- `verting mainly into soot the hydrocarbon, mixing it with air and steam, and burning the mixture in contact with a red-hot surface substantially .as-described. y.

2. In combination with the tray c pipe d and steam-pipe g, a fore-chamber b beyond such tray and pipes, and a heating-chamber a beyond such fore-chamber, all as shown and'described.
